RGB vs DVI/HDMI

Recently I bought this 32" LG 1080 LCD TV and I have a desktop comp with an ATI 46XX card that has 2 DVI and a Svideo output. the first thing I did was hook to the TV's RGB input and to the comp using a RGB to DVI adapter. But naturally I thought i might get a better picture if I went from DVI to the TV's HDMI input. So I bought a DVI/HDMI cable and gave it a try. To my astonishment at the same 1080 resolution I got a "TERRIBLE" picture (the fonts were almost unreadable and the general pic quality just totally sucked) and had to revert back to the RGB to DVI.

Can anyone tell me what happened there?

Like I said I was at same resolution with both hook ups.
 
I had the same problem. It comes down to the adapter, and the television model.

The cheaper the TV, the more likely it won't have "smart sense" to see if you're actually using your HDMI port from a DVI or RGB source. Newer, fancier models can tell, and adjust appropriately.

2nd was the adapter or cable itself.

Seeing as I didn't want to switch my TV out, the best thing to do was to use the standard DVI to RGB cable. I found that HDMI only plays well with HDMI. So if your video card has an HDMI out, it's golden. If it doesn't, don't bother (at least in my opinion).
 
FYI it's called VGA/Dsub not RGB, Unless you are talking about component and then it's ummm called component.
